Patented July 8, 1930 UNITED STATES PATEN'T- OFFICE JOHN J. HALLIWELL, OF TUGKAHOE, NEW YORK, ASSIGNOR TO R. H OE & 60., INC., NEW YORK, N. Y., A CORPORATION OF NEW YORK WATER-COOLEID INK RESERVOIR FOR PRINTING PRESSES Application filed September 25, 1926. Serial No. 137,721.

, or even in cool weather if the press becomes heated during along continuous'run, evaporation of-theink takes place, changing the character of the same and injuriously aflecting the uality of the work. 5

One 0 the objects of'my invention is to prevent such change in the ink, by reducing evaporationof the same. This is effected by keeping the ink cool, in the manner hereinafter described. Other objects of the invention will appear from the following descriptlon.

The invention consists in the novel construction, arrangement and combination of various devices, elements and parts, as set forth-in the claim hereof, one embodiment of the same being illustrated in the accompanying drawings and described in this specification. a I

In the said drawings, v Fig. 1 is an end view of one embodiment of the invention, shown with one pair of printingrcylin'ders, and ig. 2 is a side view of the same, the cyhnders eing omitted.

In carrying my invention into effect in the embodiment thereof which I have selected for illustration in the accompan ing drawings and description in this 'speci catlon, I provide a frame of suitable construction (not shown in the drawings) in which'is journaled the printing cylinder 11, which bears etched upon its surface in the usual manner the design to be printed. Below this cylinder is an ink reservoir 12, the bottom and walls I of which are of double construction, thus providing an intermediate space 13 for containing cool water or other fluid. In the preferred embodiment of the invention as shown in the drawings, I rovide means for changing the water in said intermediate space, so that the same shall be always cool, such means comprising an inlet pipe 14 and outlet pipes 15.

The cylinder 11 rotates in the ink-fountain 12, and takes up ink upon its surface. A doctor-knife or scraper 16 is suitably mounted and positioned so as to scrape against the surface of the cylinder 11 as it rotates, and remove the ink therefrom except where the etched-in lines retain the same. The web of paper to be printed (not shown in the draw ings) passes over the roller 11 and between it and the impression cylinder 17 above it, and is printed as it passes through. I

The operation-of my invention has already been sufficiently explained in the above de scription of its operation, and the advantages of the same also will be obvious from what has been above said.

'Having thus described my invention, what I I claim as new and desire to secure by Letters Patent is as follows:

Cooling means for an ink reservoir of a printing press, comprising a jacket around i said reservoir forming a space between said jacket and said reservoir adapted to contain a cooling fluid, and means for supplying the fluid, comprising an inlet'pipe for conveying said cooling fluid into said space and entering the bottom of said jacket at a point approximately midway between its two ends, and'an outlet pipe at each end of said jacket for conveying away the fluid in'said space. In witness whereof I have hereunto signed my name this 21st day of September, 1926.

' JOHN J. HALLIWELL.
